BLOWING MACHINE FOR THE MANUFACTUBE 0F FELTS.

' Application led December 18, 1926, Serial No. 155,749, and in Germany December 9, 1925. I

feed into the machine in the unit of time av larger quantity of material than is possible with the usual machines. This is of special,` importance if it is necessary to) run the machine very slowly'as required with certain starting materials. However, the increased eiiiciencyof the machine as realized by the invention is also valuable if theV machine is run at normal speed.

According to the invention the blowing machine is provided instead of with a single feeding way or track with a pluralit of such feeding tracks. .Preferably these eeding tracks which may all be constructed in the same manner are arranged above each other. In this easeit has been found suficient to provideu a single wind roller by which the material issuing from each of the feeding tracks is conveyed together into the casing in which the blowing operation takes place. "j f In order to obtain a uniform distribution of the material within the casing and a uniform deposit upon the cone or other similar member it has been found convenient not to arrange the casing with an open top as hitherto usual but to provide it with a preferably adjustable plate causing a deviation of the current of air,l an immediate action, on the material enteringy the casing, of an air current coming fromoabove and a resulting exaggerated deposit on theupper part of the cone being thusl avoided. Such deviating plate may with advantage also be used in machines having only a single Ifeeding track. In the drawing a consti-notional form of a blowing machine inaccordance with the invention is diagrammatically shown in section abut the invention is not limited to the details shown in the drawing and described in the' specification but will be defined in the claims appended to this specification.

' In the drawing 1 is the first feeding table consisting as usual of transverse lathes 2 fixed on the bands 3 passing over rollers 4. The material placed on this table is seized by feeding rollers 5 and fed to a picker 6. 7 is the usual wind breaking roller consisting of perforated sheet metal or the like; f

vThe material is further moved the pickerr to a second feeding table 8 arranged in exactly the same manner as theiirst table and, consisting of lathes 9 fixed on bands 10 and wind breaking roller.

ling at the same level.

which' pass over rollers 11. From this second` mentis arranged a wind roller'14 consisting of a drum provided with lathes 15.'

Above the feeding track arranged as just i described a second feeding track is arranged in the example shown, said trackconsisting inthe same manner of two feeding tables having the necessary feeding rollers, pickers Theparts corresponding .to those'fmentioned before are `indicated by the reference numerals 1' to 13',

respectively. Preferably this second track is operated at the same speed as the rst track.

In the construction shown no special wind roller is provided for the second feeding track, the current of air produced by the forward the material issuing from both tracks. i

In a similar manner avthird feeding track wind roller 14 being sufficient for moving I The rollers 4, 4'-, 11, 11,`feeding rollers 'i 5, 5', 12, 12', pickers 6', 18, 13', wind breaking rollers 7, 7 and wind roller 14 are adapted to be rotated by any convenient driving means not shown.

The current of air produced by the wind roller 14 when the latter is rotated projects the material into the blowing casing 16 'as indicated by the arrows.` In this casing if the machine is nsed in the manufacture of hats a rotatable cone 17 consisting of perforated `sheet metal or thelike is arranged. On this cone the material is deposited in known manner by the action of the current correspondingly# of air produced by the wind roller 14 and an exhausterlS.I If the machine isused in the feeding tracks arranged above each other,

theymayalso be arranged in any other convenient manner, for instance diametrica'lly opposite each other and issuing-into the cas- In the casing 16 a deviating yplate 19 is 'arranged above the vcone or the like, said l by said current is uniformly deposited and not substantially on the upper part of the cone as it is the case with certain'kids of starting material ifno such deviating plate is provided.
